As one of the typical layered two-dimensional transition metal dichalcogenide (TMD) semiconductors of the IVB family with a band gap value of 0.9-1.2 eV (bulk to monolayer), zirconium diselenide (ZrSe2) has been characterized in many The field has been extensively researched. As one of the typical layered two-dimensional (2D) transition metal dichalcogenide (TMD) semiconductors of the IVB family, ZrSe2 has a band gap in the visible infrared region. Its band gap value is 0.9-1.2 eV (bulk to monolayer). The properties of ZrSe2 have been extensively studied in many fields. 2D ZrSe2 with an intermediate bandgap is considered as one of the best candidates to replace silicon in nanoelectronics.
Alfa Chemistry focuses on R&D for 2D nanomaterials, primarily MXenes and MAX phase materials, black phosphorus, and other materials. Our R&D team is led by a group of PhDs with extensive research experience and worldwide studies. ZrSe2 bespoke solutions can be "personalized" to match your research objectives. Please contact us right away if you need help with your application issues.
Zirconium Diselenide Solution Synthesis and Characterization
Alfa Chemistry uses liquid-phase exfoliation, a simple yet cost-effective solution processing approach, to provide customers with tailored solutions containing ZrSe2 flakes. Exfoliation is aided by ultrasonic vibrations in the liquid media, which results in monolayer dispersions and several layers of nanoflakes. Ultrasonic treatment of high-quality single-crystal ZrSe2 flakes and high-purity dispersions is the first step in our procedure. To obtain high-quality goods with no deformation, our ultrasonic treatment technology changes the ultrasonic treatment temperature, gas environment, ultrasonic treatment power, pulse duration, and pulse dwell time. Depending on your needs, we can create single layer, few layer, multi-layer, or even bulk layered solutions.
Because of its good dispersion, stability, and performance, we will deliver ZrSe2 sheets suspended in isopropyl alcohol by default. Please contact us for further information if your research requires different solvents such as ethanol, deionized water, NMP, or others.
| Product | ZrSe2 solution |
| Solution Type | Isopropanol recommended, others available on request |
| Crystal Structure | 2H Phase |

Custom solutions are stable under ambient conditions and can be easily deposited on the substrate or surface of your choice. The crystallinity of ZrSe2 has been characterized by Raman spectroscopy, electron energy dispersive spectroscopy (EDAX) and scanning electron microscopy (SEM).

Note
We primarily ship supersaturated 2D solutions, the concentration of which varies depending on the type of 2D layer, to save shipping costs and simplify the customs protocol/border inspection process. Once the supersaturated solution is in the customer's hands, it can be diluted to a considerable volume (250-500mL). The customer can then use a simple rotational casting procedure to put the 2D layer onto the specified substrate. Please contact us if you have any additional inquiries.
